`8421 [phone]=?xx263`

Options

A. 52
B. 58
C. 54
D. 45

Answer

To find the value of the question mark (?) in the equation \(8421 + 7268 - 1487 = ? \times 263\), we will follow these steps:

### Step 1: Add the numbers 8421 and 7268
\[ 8421 + 7268 = 15689 \]

**Hint:** When adding large numbers, align them by their rightmost digits to ensure accuracy.

### Step 2: Subtract 1487 from the result obtained in Step 1
\[ 15689 - 1487 = 14202 \]

**Hint:** When subtracting, make sure to borrow from the next digit if the top digit is smaller than the bottom digit.

### Step 3: Set up the equation with the result from Step 2
Now we have:
\[ 14202 = ? \times 263 \]

**Hint:** This equation shows that the left side equals the product of the unknown value and 263.

### Step 4: Solve for the unknown value (?)
To find the value of ?, we will divide both sides of the equation by 263:
\[ ? = \frac{14202}{263} \]

**Hint:** Division can be performed using long division or a calculator for accuracy.

### Step 5: Calculate the division
\[ ? = 54 \]

**Hint:** Ensure to check your division by multiplying back to see if you get the original number.

### Final Answer
The value of the question mark (?) is **54**.
